Carb Question (Weber vs Stock)

[BigAl]

Well my poor little 85 hatch seems to be getting sicker by the day. In my most recent attempt at emissions it failed on CO by over double the limit. It has had a full tune up and a new cat installed, so being short on ideas I took it to a shop with a 5 gas analyzer to give me some ideas. They spent close to 2 hours playing with A/F mixture and couldn't get it anywhere near a passing number. Their conclusion was the carb is in need of a full rebuild or I am having problems with the air injection and they wanted a ridiculous amount of money to look any farther. I admittedly suck with carbs, but am trying to learn.

 

So my question is.. Is it worth getting a rebuild kit for the factory carb or should I go with the Weber? How difficult is the Weber to install / tune / work on versus the stock single barrel?

 

Also, this car is in CO, so it would need to be jetted for high altitude. Would the Weber need to be re-jetted and if so, how difficult is it to find and swap the jets? Lastly, which Weber (model #) do I need for an EA82?

 

I really don't want to sell her, but if I cant get this figured out in a way that makes some sort of financial sense I may have to go that way.

 

Sorry for the long winded post. Thanks in advance for any help guys.

Does Colorado allow the emissions system to be modified (as in gone)? With a Weber you would need to get rid of most if not all the emiss. sys. parts.

 

See what CO's laws are about vehicle emissions before you jump to a Weber.

If your Subie's Carb is Shot and you Need to Pass emmissions, I Believe that Maybe the Easiest & Cheapiest solution "Could Be" to obtain a Used but Known-Good Hitachi Carburetor, the same as the Stock one; maybe from a Profesional Rebuild Shop... Sometimes they can Receive your Old Carb as Part of the Price.

Kind Regards.

CO isn't terribly concerned with how everything looks under the hood as long as it runs clean. So not too worried about that piece of it.

I may end up going that way if cost gets too out of hand. I just scheduled it one more visit with a Subaru specialist so I can be sure that is the problem before I pull the trigger. Thanks for the advice.

If you have a local U pull junkyard why not go with an spfi swap. Its not that hard to do. Next month I'm getting all the parts for the spfi swap from a board member when I buy the engine from him. I'm going to a weber because I got the carb and adapter cheap. Maybe we can work out some kind of deal on the spfi intake, wire harness,distributer and fuel pump I'm getting. Then all you need to do is get a hole drilled to have a threaded bung put in the Exhaust before the cat to put the o2 sensor in.

PM me if you like.
